“It is not advisable to take aspirin for a while and then stop. Aspirin, as an antiplatelet drug, is mostly taken to prevent the occurrence of cardiovascular and cerebrovascular disease, slow the progression of cardiovascular and cerebrovascular disease and reduce restenosis in the stent. Therefore patients with cardiovascular disease who do not have gastrointestinal symptoms or risk of bleeding and can tolerate it should take it orally for a long period of time under the supervision of a physician. The practice of taking and stopping aspirin significantly reduces its efficacy and does not allow it to play its full role in preventing heart attacks and cerebral infarctions. If there is no cardiovascular disease, take aspirin with great caution, because aspirin itself has some damage to the gastrointestinal tract, prone to symptoms of gastrointestinal bleeding. Some patients may experience adverse reactions such as allergic reactions, epigastric discomfort, bleeding spots on the skin, etc. Therefore, aspirin is contraindicated in patients who are allergic to NSAIDs, suffer from asthma, are pregnant or breastfeeding. It is recommended that aspirin be taken under the supervision of a physician.
